In this article, we describe the effect of ethanolamine (EA) surface treat-ment on the inverted InP quantum dot light-emitting diodes (QD-LEDs) with inorganic metal oxide layers. The efficiency of the inverted QD-LEDs was significantly enhanced by EA treatment and optimization of the ZnO annealing temperature.
